Hi, need to submit a 1250 words essay on the topic Flow, Precipitation, and Turbidity of the Red Cedar River.
Apparatus/Tools used The set of tools for turbidity and Particle Load include a sounding line (a rope attached to a concrete weight), a timer, a supply of tongue depressors, and the aerial photo, a bucket to collect samples of river water bottles or jugs for transporting water samples to the lab, and a device for filtering known volumes of water, graduated cylinders, a supply of filters that will retain particles ≥1μm in size, metal dishes for drying and storing the filters, an oven and a desiccator to dry the filters, and a balance for measuring particle mass. Procedure In measuring turgidity and filtration of the river water sample, the procedures included, first the river water sample was collected from a Farm Lane bridge. Secondly, filter papers were obtained from the stack and placed on the manifold followed by screwing the filtering cup down tightly in order to avoid leaks. As a third procedure, a vacuum was turned on followed by measuring out 0.5L of water at a time, which was then placed into a graduated cylinder while carefully pouring it into the filter cup. Water was added to the cylinder until when the filter paper turned brown. Water from both flasks was emptied after every use. Thirty filter papers were then placed labeled metal dish. This was followed by placing the metal dish with the filter into a drying oven. It was then that the filters were tried for a period of 24 hours. Finally, with the use of a metal weighing dish, the weight of the dried dirty filter was recorded.
